LM139A: Part difference

Stephen Clark

Part Number: LM139A

Tool/software:

Hi, is part LM139ADR simply a tape and reeled version of now obsolete part LM139AD?

Or, are there other differences?

Thank you.

Hello Stephan,

The tube carrier option is inefficient and was removed as an option. The R simply means "reel"

Hello Stephen,

The LM139AD orderable part number is obsolete. The tube option is no longer available.

The LM139AD will only be available in the 2.5k reel, as Ron pointed out, the "R" stands for reel. So the LM139ADR lives on.

However, since the LM139AD orderable is discontinued, most likely the devices on the shelves will be the "classic" die.

The LM139ADR could be either the "classic" die or the new TiB die, as mentioned in the appnote, as it is in production and covered by the PCN.
